Some long time ago I started working on Bobbo - clone of very well know polish game for Atari8bit - Robbo. And here you are, the very first and short movie from gameplay. I will continue work on this adventure of amiga system coding.

Always nice to see new game on the Amiga at first I though it was about the Infogrames game which I use to play a lot.
You need hardware scroll

Thanks for comment. But the problem is that I use only os firendly way in this version game. I have plans to make raw pal version - you know asm + registers - and I did initial steps ( screen ) but it's future. So If you know any good os firendly way to scroll inside window then tell me. In my approach I just copy level bitmap ( some part of course ) into window bitmap. Furthermore on youtube video I uses slowest machine to show that is possible make non trivial os game . In this version of game there will be possibility to play in full screen mode ( with choosing screen mode of course ) but first I want to finish some unfinished parts like title ( some parts are done ), outro, gameover (done), handling different colors on diff levels, editor.

Check ScrollRaster() and ScrollVPort() graphics library functions. I think that the first use the blitter and the second the copper. So the later should be faster but it depends of the size of the area to move, if small then blitter could be enough.

Hi,

Thanks for answer.

Perhaps I didn't mentioned that scroll area is smaller then window
I don't catch the usage of ScrollVPort on WB screen, when I want to scroll some smaller area inside the window
For me ScrollRaster is useless, becasue I must redraw damaged regions (and is slow because is so general ). I used raw copy from level bitmap into game window area.
